Form layer constituting portion 50 by being formed as described above, so as to formed such, each head unit 1401 shown in Fig. 4 A, 1402nd, the composition layer constituting portion 50 of 1403 and 1,404 1 row amount (the first row in Y-direction) in the X direction (forms layer to form Portion 50a, 50b, 50c and 50d).
Next, in order to form the composition layer of the second row of each head unit 1401,1402,1403 and 1404 in the Y direction Constituting portion 50 ' (forms layer constituting portion 50a ', 50b ', 50c ' and 50d '), headstock 1100 is moved towards -Y direction.On movement Amount, when the pitch between nozzle is set into P, towards the amount of -Y direction movement P/n (n is natural number) pitch.In the present embodiment by n 3 are set to illustrate.
By carrying out such action same as described above shown in Fig. 5 A and Fig. 5 B, such, Y-direction shown in Fig. 4 B is formed On the second row composition layer constituting portion 50 ' (forming layer constituting portion 50a ', 50b ', 50c ' and 50d ').
Next, in order to form the composition layer of each 1401,1402,1403 and 1404 the third line in the Y direction of head unit Constituting portion 50 " (form layer constituting portion 50a ", 50b ", 50c " and 50d "), headstock 1100 is moved towards -Y direction.On movement Amount, towards the amount of -Y direction movement P/3 pitches.
Then, by carrying out such action same as described above shown in Fig. 5 A and Fig. 5 B, that can be formed shown in Fig. 4 C Composition layer constituting portion 50 of sample, the third line in Y-direction " (form layer constituting portion 50a ", 50b ", 50c " and 50d "), obtain Form layer 310.
In addition, on the material M shootd out from constituent material breath portion 1230, can also from head unit 1401,1402, 1403rd, more than any cell or Unit two in 1404 shoot out and supply the constituent material different from other head units.Therefore, By using forming apparatus 2000 of the present embodiment, the three-D moulding object formed by different kinds material can be obtained.
It should be noted that in the layer 501 of first layer, before or after composition layer 310 is formed as described above, Supporting layer formation material can be shootd out from supporting layer formation material breath portion 1730, form supporting layer in the same way 300.Also, be laminated in layer 501 and forming layer 502,503 ... during 50n, can also be identically formed and form layer 310 and branch Support layer 300.
The quantity of the above-mentioned possessed head unit 1400 and 1900 of forming apparatus of the present embodiment 2000 and row Row are not limited to above-mentioned quantity and arrangement.In Fig. 6 A, Fig. 6 B, as its example, diagrammatically illustrate and be configured at headstock 1100 Head unit 1400 other configurations example.
Fig. 6 A show to make multiple head units 1400 on headstock 1100 along the form that X-direction is arranged side by side.Fig. 6 B show to make head Unit 1400 is on headstock 1100 in the form of clathrate arranges.In addition, the quantity of the head unit of arbitrary arrangement is not limited to illustrate Example.
Next, the major part as above-mentioned forming apparatus of the present embodiment 2000 is further described Work bench for modeling 121.
Fig. 7 is the skeleton diagram for the work bench for modeling 121 for representing the present embodiment.Specifically, show and made formed with three-dimensional The work bench for modeling 121 of the layered product 500 of type thing is positioned over the shape for the progress degreasing of thermostat 650 that device is assigned as energy State.
As described above, the work bench for modeling 121 of the present embodiment is applied to the layer that three-D moulding object is formed by layer laminate Stack 500 and manufacture the forming apparatus 2000 of three-D moulding object, as shown in fig. 7, with for three-D moulding object the shape of layered product 500 Into forming face 121a.
Also, work bench for modeling 121 is formed as more by materials with high melting point of the fusing point higher than the constituent material of three-D moulding object Kong Zhi.Therefore, the work bench for modeling 121 of the present embodiment is configured to, as three to being formed in the top laminate of work bench for modeling 121 When tieing up the layered product 500 of moulder and carrying out degreasing, sintering, it can reduce removing material and (be contained in solvent in constituent material, viscous Mixture etc.) from the mode of (downward) volatilization in the side of work bench for modeling 121 with remove material from work bench for modeling 121 above (it is upward and Laterally) the difference (i.e. the difference of shrinkage factor) of the mode of volatilization.Thus, it is configured to suppress along with work bench for modeling 121 Top laminate and the layered product 500 of three-D moulding object that is formed carry out degreasing, sintering and send out the layered product 500 of three-D moulding object Change shape.
It should be noted that the arrow in Fig. 7 schematically shows the direction for removing material volatilization.In work bench for modeling 121 In the case of not being configured to Porous, it there's almost no and remove volatilization (downward arrow) of the material from the side of work bench for modeling 121, Less shunk compared with other parts the side of work bench for modeling 121.
In addition, the work bench for modeling 121 of the present embodiment can load and unload relative to forming apparatus 2000, and in forming face 121a Formed with the fusing point organic film 600 lower than constituent material.Therefore, be configured to, such as along with the composition than three-D moulding object Layered product 500 at low and higher than the fusing point of organic film 600 temperature of the fusing point of material to three-D moulding object carries out degreasing, burnt Knot, the organic film 600 can together be removed with removing material, can particularly effectively suppress the layered product of three-D moulding object 500 deformations, and the layered product 500 of the three-D moulding object after degreasing, sintering is separated from work bench for modeling 121.This Be because, although degreasing, sintering when three-D moulding object layered product 500 shrink, by forming organic film 600, so as to Suppress the layered product 500 of three-D moulding object in the state of by forming face 121a concavo-convex constraint because of degreasing, sintering in constituent material And shrink.Particularly, in the case where work bench for modeling 121 is configured into Porous as the present embodiment, due to forming face 121a bumps have the trend of increase, therefore it is especially big to form effect caused by organic film 600.
And then by enabling work bench for modeling 121 to be loaded and unloaded relative to forming apparatus 2000, so as in order to carry out degreasing, When sintering and the layered product 500 of three-D moulding object is moved to energy imparting device (thermostat 650), it can be worked together with moulding Platform 121 moves together.Therefore, it can suppress to unload three-dimensional from work bench for modeling 121 along with order to be placed in thermostat 650 The layered product 500 of moulder and make the layered product 500 of the three-D moulding object damaged.
It should be noted that it is unquestionable, it can also prepare to be pre-formed with the work bench for modeling 121 of organic film 600, and The layered product 500 of three-D moulding object is formed in the work bench for modeling 121.But, can also prepare to be formed without organic film in advance 600 work bench for modeling 121, before the layered product 500 of three-D moulding object is formed, from supporting layer formation material breath portion 1730 shoot out supporting layer formation material and form organic film 600 in forming face 121a, afterwards, form the stacking of three-D moulding object Body 500.Then, the work bench for modeling 121 for organic film 600 being formed to forming face 121a like this is also contained in the present invention In be self-evident.
In addition, the organic film of constituent material " fusing point be less than " refers to, covering forming face 121a at least a portion and comprising Film of the fusing point less than the organic principle of constituent material.
Here, the organic film 600 for being formed at the work bench for modeling 121 of the present embodiment contains acrylic resin.Due to propylene The fusing point of acid resin is low and is not easy residual source in the acrylic resin on work bench for modeling 121 after degreasing, sintering Carbon, therefore, it is possible to suppress to be mixed into the carbon as impurity in the layered product 500 of the three-D moulding object after degreasing, sintering.
But, the forming component of organic film 600 is not particularly limited, and in addition to acrylic resin, can also use polyester Resin etc., and various kinds of resin can also be contained.
In addition, organic film 600 can also be higher than the composition of constituent material containing fusing point.Because if organic film 600 is containing molten Point then takes off higher than the composition of constituent material in the layered product 500 of the three-D moulding object to being formed on work bench for modeling 121 Fat, sintering in the case of, in degreasing, sintering after on work bench for modeling 121, dystectic composition as release liner and Equably remain on work bench for modeling 121, three-dimensional particularly simply can be separated (in the short time) from work bench for modeling 121 and made The layered product 500 of type thing.
It should be noted that being not particularly limited for " fusing point is higher than the composition of constituent material ", such as pottery can be used Porcelain (aluminum oxide, carborundum and zirconium oxide etc.).
In addition, the materials with high melting point in work bench for modeling 121 is preferably included in aluminum oxide, carborundum and zirconium oxide It is at least any of.Because their fusing point is high, even if being also difficult to deform at high temperature, therefore can particularly effectively suppress companion As the layered product 500 of the three-D moulding object to being formed on work bench for modeling 121 carries out degreasing, sinters and makes the three-dimensional modeling The layered product 500 of thing deforms.
So, the forming apparatus 2000 of the present embodiment passes through the shape on the forming face 121a of such work bench for modeling 121 Three-D moulding object is manufactured into the layered product 500 of three-D moulding object.Then, by such structure, when in work bench for modeling When 121 top laminates and the layered product 500 of three-D moulding object that is formed carry out degreasing, sintering, it can reduce and remove material from making The mode of the side of type workbench 121 volatilization and the difference for removing the mode that material volatilizees above work bench for modeling 121.Thus, this reality The forming apparatus 2000 for applying example is configured to suppress to make along with the three-dimensional to being formed in the top laminate of work bench for modeling 121 The layered product 500 of type thing carries out degreasing, sinters and the layered product 500 of three-D moulding object is deformed.
And then the forming apparatus 2000 of the present embodiment is due in the work bench for modeling 121 that can be loaded and unloaded relative to the device Forming face 121a formed with fusing point less than three-D moulding object constituent material organic film 600, therefore, be configured to along with right The layered product 500 of three-D moulding object carries out degreasing, sintering, can remove the organic film 600 together with removing material, and can make three The layered product 500 of dimension moulder is easily separated from work bench for modeling.
Next, process for using figure, the manufacture method of the three-D moulding object to using the progress of above-mentioned forming apparatus 2000 One example illustrates.
Here, the flow chart of the manufacture method for the three-D moulding object that Fig. 8, which is the present embodiment, to be related to.
As shown in figure 8, in the manufacture method of the three-D moulding object of the present embodiment, most start to obtain three in step s 110 Tie up the data of moulder.Specifically obtained in application program, such as from personal computer performed etc. and represent that three-dimensional is made The data of the shape of type thing.
Next, every layer of data are created in the step s 120.Specifically, in the number for the shape for representing three-D moulding object In, cut into slices according to the moulding resolution ratio of Z-direction, corresponding each section generation bitmap (bitmap) data (number of cross-sections According to).
Next, in the case where having prepared to be formed without the work bench for modeling 121 of organic film 600, in step s 130, Supporting layer formation, which is shootd out, from supporting layer formation material breath portion 1730 forms organic film on forming face 121a with material 600.But, in the case where having prepared to be pre-formed with the work bench for modeling 121 of organic film 600, this step can be omitted.
Next, in step S140, the data based on every layer generated in the step s 120, three-D moulding object is formed Layered product 500.Then, by step S150, repeat step S140 and step S150 up to every layer of the end of data, in moulding The layered product 500 of three-D moulding object is completed on the forming face 121a of workbench 121.
It should be noted that in step S140~step S150, in the manufacture method of the three-D moulding object of the present embodiment In, without especially assign energy in the case of make naturally solvent volatilization come formed the layered product 500 of three-D moulding object (Gu It is fixed to form layer constituting portion 50), but energy can also be assigned fix composition layer constituting portion 50 by heating etc..
Next, in step S160, three-dimensional modeling is taken out from forming apparatus 2000 together with work bench for modeling 121 The layered product 500 of thing, it is placed in the thermostat 650 that device is assigned as energy and carries out energy imparting (heating).Need It is noted that the organic principle for removing organic film 600 is decomposed in this step.
Then, finally, in step S170, improve thermostat 650 energy output and heated three-dimensional moulder layer Stack 500, terminate the manufacture method of the three-D moulding object of the present embodiment.
It should be noted that step S160 be energy corresponding with degreasing assign process in the case of, step S170 with It is corresponding corresponding to the heating process for condensing or melting, it is the feelings that energy corresponding with degreasing and condensation assigns process in step S160 Under condition, step S170 is corresponding with the heating process corresponding to melting.In addition, make the degreasing of layered product 500 of three-D moulding object complete Into situation or condense in the case that the situation etc. completed need not condense, melts, step S170 can be omitted.
So, the manufacture method of the three-D moulding object of the present embodiment has：Using above-mentioned work bench for modeling 121 in its shape The layered product formation process (step S140) of the layered product 500 of three-D moulding object is formed on into face 121a and to three-dimensional modeling The energy that the layered product 500 of thing assigns energy assigns process (step S160).
Therefore, to (being higher than the high-melting-point material of constituent material with fusing point in layered product formation process in energy assigns process Material is configured to Porous) in the layered product 500 of three-D moulding object that is formed in the top laminate of work bench for modeling 121 taken off When fat, sintering, the mode for removing material from (downward) volatilization in the side of work bench for modeling 121 can be reduced with removing material from moulder Make the difference for the mode that platform 121 volatilizees (upwards and laterally) above.Thus, it is possible to suppress along with work bench for modeling 121 Layer laminate and the layered product 500 of three-D moulding object that is formed carry out degreasing, sintering and the layered product 500 of three-D moulding object occurs Deformation.

It should be noted that although the work bench for modeling 121 of above-described embodiment is low formed with fusing point on forming face 121a In the organic film 600 of constituent material, but it is not limited to such structure.
Here, Fig. 9 and Figure 10 are to represent the work bench for modeling with the different structure of the work bench for modeling of above-described embodiment 121 121 skeleton diagram, it is figure corresponding with Fig. 7 of the work bench for modeling of above-described embodiment 121.
Work bench for modeling 121 shown in Fig. 7 is configured to Porous, and is configured to in the top laminate of work bench for modeling 121 And when the progress of layered product 500 degreasing, the sintering of the three-D moulding object formed, removing material can be reduced and (included in constituent material Solvent, adhesive etc.) from the mode of (downward) volatilization in the side of work bench for modeling 121 with removing material from work bench for modeling 121 The difference (i.e. the difference of shrinkage factor) of the mode of face (upwards and laterally) volatilization.This is based on, and volatile ingredient (removing material) can move Into the hole with the Porous for the work bench for modeling 121 for being configured to Porous.And then the hole is connected, in such as Fig. 7 As shown in arrow etc., the side (downside) different from forming face 121a sides is being communicated to from forming face 121a sides (upside) In the case of, can particularly effectively reduce from the side of work bench for modeling 121 (downward) with from work bench for modeling 121 (upwards and The difference for the mode laterally) volatilized.
Here, the work bench for modeling 121 shown in Fig. 9 be also similarly configured to the work bench for modeling 121 shown in Fig. 7 it is porous Matter, to be communicated to the side (downside) different from forming face 121a sides from forming face 121a sides (upside).
Here, the work bench for modeling 121 shown in Fig. 9 is different from the work bench for modeling 121 shown in Fig. 7, in forming face 121a It is formed without organic film 600.In the case of such structure, when composition Porous and forming face 121a emptying aperture is formed at Aperture it is larger when, carry out degreasing, sintering when, the constituent material of three-D moulding object enters the emptying aperture, the layer of three-D moulding object Stack is shunk in the state of this composition material is bound.Therefore, along with degreasing, sintering, the layered product of three-D moulding object has May deform etc..
However, in the work bench for modeling 121 shown in Fig. 9, the emptying aperture of Porous is formed, and is formed at forming face 121a Average pore size be less than more than 1 μm 5 μm.It should be noted that average pore size is sentenced such as by mercury penetration method It is disconnected.By making average pore size be more than 1 μm, solvent, adhesive etc. can be made fully to be waved from the downside of work bench for modeling 121 Hair.In addition, by making average pore size be less than 5 μm, the constituent material that can suppress three-D moulding object enters the emptying aperture, can press down The layered product for making the three-D moulding object when carrying out degreasing, sintering is restrained to the shape of the emptying aperture in the constituent material of three-D moulding object Shunk under state.That is, the work bench for modeling 121 shown in Fig. 9 is configured to make solvent, adhesive etc. from work bench for modeling 121 downside is fully volatilized, and can suppress concomitantly to make the layered product of three-D moulding object deform etc. with degreasing, sintering.
It should be noted that such as can by the ethanol that drips on forming face 121a liquid, whether carry out the liquid It is seeped into the confirmation in the face of forming face 121a opposite side etc. etc. to judge whether to be communicated to and the shape from forming face 121a sides The mode of the side different into face 121a sides is configured to Porous.
In addition, though the work bench for modeling 121 shown in Fig. 9 be configured in the same manner as the work bench for modeling 121 shown in Fig. 7 from Upside is communicated to downside, but the work bench for modeling 121 shown in Figure 10 is configured to be provided with layer from the forming face 121a sides of upside The region of stack 500 is risen, and is not only communicated to downside, but also is communicated in side and forming face 121a sides and is not provided with The region of layered product 500.
